CENTRIFUGAL ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 489,198, dated January 3. 1893. Application filed April 24, 1891. Serial No. 390.328. (No model.)

vide means for insuring the even discharge `of the material being treated inthe vessel;

and myinvention consists in the features and details of construction hereinafter' described and claimed.

In the drawings, Figure l is a vertical elevation partly in section of an apparatus provided with my improvements; Fig. 2 a vertical central section of the revoluble vessel taken in line 2 of Fig. l; and Fig. 3 a plan view of the removable guide and wearing ring.

The revoluble vessel A is supported upon and revolved by the shaft B, and is preferably inclosed bya curbing C, as shown, orin any other Way.

v The preferable form of the vessel is shown more particularly in Fig. 2. In use the vessel is but slowly worn alongthe interior at thebottom and lower parts of the side, but

near the. upper end on the interior side, and

`more particularly in the vicinity of the discharge orifices D, the wear is very great, and itis therefore desirable to provide means for removing this partof the vessel from time to time, without necessitating the reconstruction of the entire vessel. To accomplish this, I provide a ring E, preferably of theform shown in Figs. 2 and 3, fitting the inside of the 'upper end of the vessel, which is preferably enlarged to receive it. The ringis of asize and shape to fit the vessel more or less closely, and is provided with holes e, corresponding in position with the discharge orifices D, so

, that; when this ring4 is placed in the Vessel,

the holes in the ring shall correspond to or register with those in the vessel. When this ring becomes Worn by use to such an extent i as to be no longer properly serviceable, it may be taken out by first removing the cover F,

4and a new ring may be substituted therefor, t-helcoverbeing afterward again fastened in place, thereby holding the ring in position. This ring is also preferably provided with a number of guide plates G, which may be made integral with the ring, or separate therefrom and fastened thereto, as may be desired. These plates are preferably made in the form shown in the last two figures of the drawings, there being one plate at either side of each of the holes, extending out from the surface of the ring a suitable distance, and inclining upward as shown, each pair of plates converging or approaching each `other, and

forming a channel contracting in width as it '4 By means approaches the holes or orifices. of the channels formed bythe plates, the material is guided or directed toward the discharge orifices, and the uniform and equal discharge of the material is facilitated thereby, and any uneven accumulation of the ma. terial prevented.

While I have shown the plates secured to the removable ring, the ring may be dispensed with, and the platesstill used within the Vessel to form the channels as before described.

I claim:

1. A vessel for the centrifugal treatment of powdered or finely divided substances for the separation of metallic or mineral-bearing particles, provided with discharge orifices, and channels for guiding the material to the discharge orifices, substantially as described.

2. In a vessel for centrifugally treating powdered or finely divided substances for the separation of metallic or mineral-bearing particles, provided with discharge orifices, plates forming'channels for guiding the material to the discharge orifices, substantially as described. i

3. In a vessel for the lcentrifugal treatment of finely divided substances for the separation of metallic or mineral-bearing' particles, provided with discharge orifices, a removable ring fitting inside thevessel and having holes or openings corresponding to the discharge orifices, and a channel for guilding the material to the holes or openings, substantially as described.

4. In a vessel for the centrifugal treatment nels for guiding the material to the holes or of powdered or finely divided substances'for openings, substantially as described. the separationv of metallic or minerabbearigg i l particles, provided with discharge orifices, a ORRIN 13. PECK.
